(Cl. l9822) In transferring glassware from a forming maby the take-out device 2, which places them on a chine to a leer, it is desirable to get the glass into rotating table 3. This table is continuously rothe leer as soon as possible, but it is also desirtated, and at a relatively high speed, to advance able that the glass articles be kept from contactthe ware to the leer as soon as possible. Ac-

Of course the table may be rotated employ two revolving tables, with a fixed guide to by any desired means,and such means, per se,

The table 6 is also prefemployed to direct the ware from the first table erably driven by a motor 10 through reduction 20 to the second table. This guide acts as a drag gearing 11; the speed of the second table being On the articles, s ows d w their movement, and considerably slower than that of the first table. sometimes causes them to contact with each If th t t m t t d t th samespeed th A150, the sp d of rav l of the articles then the articles on the second table would be slows down at the point of transfer from the first spaced apart almost t a distance as o 5 table to the second table, and this often results t first t and hence would ot be properly so. in the articles contacting with each other at this pgsitioned for feeding to th 1eer By rotating Point And y Often remain in this undeSiT- the second table at a slower speed it is apparent able rela While y are being pushed into that the articles may be arranged on the second the lee d during their travel h ou h t e leer. table at the desired distance apart for feeding an Th p p f h present i v n is to into the leer.

This pivot is preferably located on 110,

the line of tangency of the two tables, as shown, but of course the invention is not limited to this particular pivotal point. Secured to the lower end of the bracket 15, slightly above the surface of the table 3, is an arm 16, which is preferably formed with a bend 1'7, so that it is somewhat plow-shaped; the point of the plow being located where the articles are. actually pushed from the first table to the second table.

The arm 16 has its end turned downwardly, as indicated by numeral 18, and is loosely connected with the upwardly extending arm 19 of a bell-crank lever which is pivoted on a bracket 20. The arm 21 of the bell-crank lever is pivotedto the upper end of a link 22. lfhe lower end of this link is pivoted to a lever 23 which has its opposite end pivotally mounted on a bracket 24. In the specific embodiment illustrated, a cam 25 is arranged beneath the lever 23, and the con-. tinuous rotation of this cam causes the lever to be intermittently raised and lowered, whereby the vibrator arm 1'7. is moved back and forth. The cam 25 is preferably rotated by a motor 26 through reduction gearing 27;. Itwill be understood that the invention is in no sense limited to. the particular mounting ofthe. vibrator arm or molds l by the take-out device. 2, whichv places.

table. It is not essential-to thisinve tion that the arm be provided witha, bendtogiveit a plow effect, but it, is desirable, The desirable fe fiu amn r ti n s hpwn F re: I 2. At the point; of-tangency two; articles; are

shown in full lines alrnost touching, and as the arm. provided with, the bend; 1'7; moves forward the articles arenot only pushed over to the other tablebut also they. aremoved slightly awayfrom each other, as indicated; in dotted lines. Thus the articles are, more or less positively spaced the desired distance apart on the second table. Of course this spacing is approximatelythe spacing desiredbetween the articles as they -are carried through the leer, and it is apparent thatin being pushed into the leer they will remain spaced substantially the distance that they are spaced when initially arranged on the second table.

From the above description it will be apparent that I have devised a very simple device for transferring articles from one rotary table to another, in the process of transporting ware from a forming machine to a leer, and that the device will eliminate liability of contact between the articles being transferred and properly space them on the second table ready to be fed into the leer.

In accordance with the patent statutes I have described what I now believe to be the preferred form of the invention, but obviously many changes and modifications may be made without departing from the spirit of the invention, and all such changes are intended to be included within the scope of the appended claims.

What I claim is:

1. Apparatus for transferring glassware including a continuously rotating table receiving ware from a forming machine, a second continuously rotating table associated with the firstmentioned table, and a member periodically moved back and forth for transferring ware from the first-mentioned table to the secondmentioned table, said member operating independently of the rotary position of the secondmentionedtable.
